Angelborg, C., N. Slepecky, H. C. Larsen and L. Soederberg. Colored microspheres for blood flow determinations twice in the same animal. Heart Res. 27:265-9, 1987.
The regional cochlear blood flow has been studied in the rabbit cochlea by mapping the distribution of non-radioactive microspheres in serial sections of plastic embedded cochleas. By using microspheres of two different colors injected at two different times, it is now possible to measure the 'regional' cochlear blood flow twice in the same animal.
